DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 481,357, dated August23, 1892.

Application filed September 25, 1891- Serial No.406,849. (No model.)

.To all whom it may concern:

Be it known that I, ALMON HUNT, a citizen of the United States, residingat the city of Atlantic, in the county of Cass and State of Iowa, haveinvented certain new and useful Improvements in Draft-Equalizers; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilledin the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to improvements in draft-equalizers; and itconsists in the peculiar construction and combination of the parts thatwill be more fully set forth hereinafter, and particularly pointed outin the claim.

My invention is particularly adapted to be used on harvesting-machinesand other agricultural machines in which there is a heavy side draft;and the objects of my invention are to provide a draft-equalizer whichwill over come the side draft of self-binding harvesting-machines andwhich can be readily converted from a four-horse to a three-horseequalizer when desired. I attain these objects by the device illustratedin the accompanying drawings, in which Figure l is a perspective View ofthe draftequalizer; Fig. 2,a detail view of the springsupport, and Fig.3 a detail view of strengthening-piece for tongue.

Similarletters refer to similar parts throughout the several views.

A represents a pole or tongue of a selfbinding harvesting-machine ofordinary construction.

F is a spring-support made of steel, having its inner end firmly securedto the tongue and its outer end located between the inner ends of thelevers B and O. The bar E is secured to the tongue and projects from theoff side thereof.

D is a strengthening-piece composed of the plate I, having theperforated boss g and lip n. The lip 01. bears against the side of thetongue and the boss g projects upward into the bar E. The parallel ironstraps a are firmly secured at their inner ends to the outer end of thebar E, one to the top side and the other to the bottom side of the barE.

B and O are two levers, which are pivoted at their inner ends by meansof a common bolt d to the outer end of the spring-support F and outerends of the iron straps o the upper strap a resting upon the top side ofthe lever B and the lower strap a under the lever C. 7

P is alever pivoted to the inner end of the bar E by means of the bolt6, which passes through the strap d, lever P, plate 15, and tongue.

The parallel bars H are pivotally connected at their forward ends to thelever C and at their rear ends to the lever P. The parallel bars H arepivotally connected at their forward ends to the lever B and at theirrear ends to the lever P.

To the outer end of the lever O is secured the doubletree G and to theouter end of the lever B is secured the doubletree G. Each doubletreehas secured to it in the usual manner two singletrees.

The drawings show an equalizer adapted for four horses; but by movingthe rear ends of the bars H and securing them to the lever P byinserting the pivot through the aperture a, so that the bars H willoccupy the posit-ion as shown by the broken lines, and by substituting asingletree in the place of the doubletree G a three-horsedraft-equalizer is provided.

The operation of my invention will be very readily understood from theforegoing description and the accompanying drawings.

Having described my invention, what I claim as new, and desired tosecure by Letters Patent, is

The herein-described draft-equalizer, composed of the tongue A, the barE, secured to the tongue, the spring-support F, secured to the tongue,the levers B and (J, pivoted at their inner ends to the outer ends ofthe bar E and support F by a common pivot, the lever P, pivoted to thebar E, the parallel bars H, pivoted at their forward ends to the lever Cand at their rear ends to the lever P, and the parallel bars A, pivotedat their forward ends to the lever B and at their rear ends to the leverP, all combined substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ALMON HUNT.
